Figure 5. Effect of visuo-motor skill training on EEG–EMG coherence on the trained and untrained muscle.

Traces showing the size of corticomuscular coherence on the trained and untrained limb, before and after the visuo-motor skill training session in a single subject. On each graph, the ordinate shows the size of EEG–EMG coherence and the abscissa shows the frequency domain (Hz). The 95% confidence limit is given by horizontal dashed line.
